In this article, we will explore the usage of the Get-AzSynapseKustoPoolLanguageExtension cmdlet in PowerShell and its importance in the Windows environment. The Get-AzSynapseKustoPoolLanguageExtension cmdlet allows us to retrieve the language extensions available in an Azure Synapse Analytics dedicated SQL pool (formerly SQL Data Warehouse). These language extensions enable us to execute scripts and queries in various programming languages within the dedicated SQL pool.

By using the Get-AzSynapseKustoPoolLanguageExtension cmdlet, we can access the language extensions and their properties, such as the language name, version, and whether the extension is enabled or not. This information is valuable for understanding the capabilities of the dedicated SQL pool and determining which languages can be used for script execution.

Examples:

Example 1: Retrieve all language extensions in a dedicated SQL pool

$resourceGroupName = "YourResourceGroupName"
$workspaceName = "YourWorkspaceName"
$poolName = "YourDedicatedSQLPoolName"

$languageExtensions = Get-AzSynapseKustoPoolLanguageExtension -ResourceGroupName $resourceGroupName -WorkspaceName $workspaceName -PoolName $poolName

$languageExtensions

This example demonstrates how to retrieve all language extensions available in a dedicated SQL pool. Replace "YourResourceGroupName", "YourWorkspaceName", and "YourDedicatedSQLPoolName" with the actual names of your resource group, workspace, and dedicated SQL pool.

Example 2: Check if a specific language extension is enabled

$resourceGroupName = "YourResourceGroupName"
$workspaceName = "YourWorkspaceName"
$poolName = "YourDedicatedSQLPoolName"
$languageName = "YourLanguageName"

$languageExtensions = Get-AzSynapseKustoPoolLanguageExtension -ResourceGroupName $resourceGroupName -WorkspaceName $workspaceName -PoolName $poolName

$languageExtension = $languageExtensions | Where-Object { $_.LanguageName -eq $languageName }

if ($languageExtension.Enabled) {
    Write-Host "The $languageName language extension is enabled."
} else {
    Write-Host "The $languageName language extension is not enabled."
}

This example shows how to check if a specific language extension is enabled in a dedicated SQL pool. Replace "YourResourceGroupName", "YourWorkspaceName", "YourDedicatedSQLPoolName", and "YourLanguageName" with the actual names of your resource group, workspace, dedicated SQL pool, and language.
